We have Four (six ?) armies:
Eldar (poss split into Bel Tain and Ulthwe)
IG (sub divided into DKK, Devos IV PDF, Valhallans, and then sub bits of ASL, Vostroyans & Cadians)
(And a theoretically legal Inquistorial warband as well)
Heretics (the Bloodcoats) and Renegades (the Tigers).
(Now as part of the H&R army there is also a legal Emperor's Children (Chaos Spaze Muhreen) army.)
Dark Eldar (the infamous Cabal of the Broken Teaspoon)
And a number (five) of players:
Zzzzzz, CNJ, AD(HD), MCA & MCH.
So; does everyone choose an army at the beginning and stick with it, learning how it works and so forth ?
Or do we let people choose a different one each time (with the order of the choosers pre-determined on a rolling programme) ?
Or do we randomise the entire process ?
Or something else ?
Do feel free to offer an opinion, otherwise I will just make it up. And I will not be fair or equitable, I will have you all do my bidding, Mwa ha ha... (exits vertically on a flying chair, stroking a dog dressed as a white persian cat)
